Letters Patent No. 81,848, dated September 1, 1868.

IMPROVEMENT 1N SASH-FASTENINGS.

TO ALL WHOM ITl MAY CONCERN:

Be it known that I, FELIX WALKER, of Memphis, in -the county of Shelby, and State of Tennessee, have invented a new and useful Improvement in Fastening for Window-Sash and Sliding Doors; and I do hcneby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use thc same, reference being had to the accompanying drawings, forming part of this specification, in Which- I Figure 1 represents a window having my improved sash-fastening attached on opposite sides, one for keep- `ing the sash up, and the other to prevent it from being raised.

Figure 2 is an enlarged view of the fastening in position for holding up the sash.

Figure 3 represents the fastening provided with an eccentric-button to keep it from acting, when'desired.

Figure 4 represents a modification of the device, with both eccentrics hung on'one pivot.

Similar letters of reference indicate corresponding parts.

This invention relates to a new device for fastening and securing sash and sliding doors, and to prevent sash and doors from rattling, from the action of -Wind or otherwise, andconsists in the useot` a. duplex eccentric` balance-wheel or wheels, secured to the frame of a window or door, (or it may he secured to the sliding sash or` door, as may be desircd,) by a yoke or keeper, made of brass, or any other suitable material.

The yoke or keeper can be made to hold only one wheel, or it maybe made deep enough to receive two Wheels on the same pivot-screw, and will serve to retain the sash or door at any height desired, and which sash or door cannot be moved up or down without first turning one ofthe eccentric-wheels.

Thus, hoist the sash or door to the point desired, then turn one .wheel up, and theother wheel down, and the sash or door will be securely held in that position, and cannot be run up or down until both wheels are turned in the same direction.

The yoke or keeper may be vmade long enough to receive two wheels in a line.

The i yoke or keeper may be secured to the frame ofthe window or door, or it may besecured to the sash or door, as may be desired.

In 5g. 1, an eccentric balance-wheel, a, is represented, in position to prevent the sash from falling when partially raised to any point desired, and in the same figure, on the opposite side of the lower sash, the eccentric balance-wheel a is represented in position to` prevent the sash from being raised.

In fig. 2, the eccentric, a, enlarged, is also represented in the position for preventing the sash from falling or sliding down when hoisted partially or wholly;

The eccentric is hung on a pivot. d, in a yoke, bracket, or keeper, e, that is fastened at the ends, by screws,

to the sash, door, or frame.

The pivot d is a screw, which passes throughboth the keepenand eccentric into the wood, to aid in securing all iirmly.

These partsv are made ofiron, brass, or any other suitable material.

The eccentric balance-wheel c'an be applied to either side of aldoor or window-sash, for the purpose of preventing the sash from moving up or down, or ecccntrics may be placed on opposite sides of a sash, one for preventing it from rising, and the other from falling.

A duplex fastening may be made by hanging the two ccccntrics on one pivot, on one side ofthe sash, ina curved yoke or bracket, as shown in red, g. 4, for edecting both objects by one fastening.V i

An cccentriebutton, e, may be attached, for the purpose of keeping one ofthe eccentrica from acting, when desired, while the other eccentric only shall operate, as shown in iig. 3.

The eccentric may be loaded, or made heavy on one side, in order to balance or counterpoise it.

This device may be made of malleable cast iron, or other` metal, very cheap. It is convenient and sure in its operation, isnot liable to'gct out of order, and isvery durable.

A keeper maybe made and secnrely'fastened at one end only, and only long enough to receive and hold the pivot-screw and eccentric, thereby leaving the eccentric more exposed to be operated on with the hand.

The keeper and eccentrics maybe permanently attached, with screws, to a piece of wood moulding, about six inches in length, and the latter secured to the' side of the Window-frame. By this means the eccentrics can be accurately placed at the ;properdistance from the sash, to secure their vcertain action. The strip of wood also serves as a guide to a loose running sash. i

Having described my invention, I claim as new, and desire to secure by L ctters'Patent- The eccentric duplex balance-wheels a a, pivoted tothe sash upon the same pivot, in combination with the curved keeper e, constructed and operating as described for the purpose specied.

" Y t, .FELIX WALKER.`
